It took more than 100 firefighters about one hour to knock down the flames, officials said.

Several lanes of Desoto Avenue and Sherman Way were temporarily shut down while firefighters mopped up the scene.

Fire officials said there are four businesses inside of the strip mall. The interior locations, including a check-cash business, had the most damage.

"The check-cashing place and the cash-for-gold place are more heavily damaged and it's going to take a long time. They're going to have to go through that whole fire rehabilitation process," said Capt. Daniel Curry of the LAFD.
